Looking for a mixer/controller to go along with my S2 4 deck mapping

Currently the S2 is my only controller and I am looking to expand. After getting the DJTT 4-Deck mapping, I realize the drawback to having only 2 sets of EQs. I have looked into the Xone K2 and it would be able to add the EQs for decks C/D as well as extra FX controls, and it also has the 4x4 grid. However, it seems a bit on the expensive side.

My other option would be spending more on a mixer. Are there any mixers that can be controlled by Traktor, while still providing me with the ability to use the S2 as a controller? This would remove the need for me to use the EQs on my S2 totally. My thinking is that getting a mixer might be a better investment for when begin to expand and purchase CDJs or something along those lines.

-Thanks

I am about to buy the s2 and I already have a kontrol x1 I was told before I could use the kontrol x1 along with the s2 to control all four decks… currently searching the forums to make sure this is true before I go ahead and buy the s2… search it up yourself and lets see if we can get a for sure answer because the x1 is awesome and not too expensive
